Oshu, Iwate

The Oshu Fujiwara clan built their capital in Hiraizumi — a northern court to rival Kyoto, some said, at the edge of the world the Japanese state then claimed. Their golden age lasted a century. The ruins of their temples are now a UNESCO World Heritage Site. But the memory extends further south, to Mizusawa.

Each May, the streets of Mizusawa fill with people in Heian court costume — warriors and courtiers moving through a city that has otherwise kept pace with the twenty-first century. This is a community staging its own history, not for tourist consumption but because the story deserves to be walked through.

If you have already visited Hiraizumi and stood at the Konjikido shrine, come here afterward. The Fujiwara story continues here, in a different register — through living people who have decided, season after season, not to let it end.

Black, heavy, made to last a lifetime. Oshu in Iwate is the home of Nanbu ironware, known above all for iron kettles. Nanbu ironware is plain, black and substantial, but the more you use it the more character it takes on; it is handed down for decades, sometimes across three generations. Boil water in an iron kettle and the water grows mellow, with iron in it too, utility and beauty both. The making is dizzying: a mold is built from sand and clay, and molten iron poured in. The fine dots on the surface, the "hailstone pattern," are pressed one by one by hand. The tradition dates to the seventeenth century, beginning when the Nanbu domain invited kettle-masters for the tea ceremony, four centuries ago. You can tour the foundries: the orange glow of molten iron, the craftsman's movements without waste. A place where tools made to last a lifetime are made.
